Abstract
A toner for developing electrostatic latent images comprising: colored resin particles which include a binder resin and a colorant, and hydrophobic titania micro particles which are obtained by surface treating of anatase-type titania micro particles having average primary particle size of 30 to 90 nm with a hydrophobicity imparting agent and satisfy following relationship: EQU S=1125/D+k wherein S expresses BET specific surface area (m.sup.2 /g) of hydrophobic titania micro particles, D expresses average primary particle size (nm) of anatase-type titania micro particles, and k expresses a constant of 0 to 60.
